PT1000 Temperature and LM3 reactor - managementboy - 08.07.2017
Hi,
how do I add a LM3 reactor connection with a PT1000 temperature sensor?
Thanks!!

HI! Connect your PT1000 sensor between GND and Resistive input №1 (for example). Go to Logic machine -> Reactor tab, click on RI1 row, set group address, set "send delta" and press SAVE. then it should work correct

Reactor v3 has no Resistive inputs. You can try connecting it shown on this picture: https://en.wikipedia.org/wiki/Voltage_divider#Resistive_divider
Where R1 is PT1000 sensor, R2 is fixed 1K resistor, Vin goes to 24V, Vout goes to Analog input. This way you can calculate sensor's resistance and convert it to temperature.
